To all whom it may concern:

Be it known that I, Ross C. HAWK, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Gas-Burners; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to gas-burners.

The object of my invention is to provide a burner in which provision is made for the regulation of the admission of the air and gas to such a degree of nicety that the air and gas are mixed in such proportions as to give the most perfect combustion and the greatest number of heat-units for the amount of gas consumed.

To these ends my invention comprises,

Vgene'zrally stated, a hollow shell or casing having a series of apertures formed in the walls thereof at suitable intervals apart, a chamber surrounding said shell with a gasinlet leading thereto, a sleeve surrounding said casing and movable thereon so as to control the passage of gas through said apertures into said casing, and means for admitting air to said casing together with means for controlling the amount of air.

In the drawings Figure 1 is a plan view of my improved burner; Fig. 2 is a longitudinal section thereof; and Fig. '3 is an end-view.

In the drawings, the numeral 2 designates a portion of a casing or shell which may be formed of cast-metal, having the flange 3 formed integral therewith. The other portion of the shell desi nated by the numeral 4, may be formed of brass with the apertures 5 formed therein. These apertures are preferably arranged spirally for the purpose more fully hereinafter set forth. The sections 2 and 4 of the shell or casing have their adjoining ends abutting, and surrounding the section 4 is the casting 6 which forms the annular gas-chamber 7. This casting is provided with the inlet 8 to which a suitable gas supply pipe may be connected.

Screws 9 pass through the flange 3 and engage the threaded seats 10 i-n the casting 6 to secure the section 2 thereto.

The casting 6 has the threaded opening 11 with which the threads 12 on the sleeve 13 engage. This sleeve 13 fits neatly over the section 4 of the shell or casing and the forward end of said sleeve controls the apertures 5 and the amount of gas admitted to the shell or casing. The sleeve 13 has the flange 14 which is adapted to bear against the outer face of the casting 6, when the sleeve 13 is advanced to its extreme forward position.

As stated above the apertures 5 are arranged spirally and at the same pitch as the pitch of the threads 12 of the sleeve 13 so that by the turning of said sleeve a quarter or a half turn, a certain number of apertures can be opened according to the distance they are arranged from each other. In this manner the entrance of the gas can be controlled with great accuracy.

Secured to the flange 14 of the sleeve 13 is the cage 15, which is secured to said flange by the screws 16. The cage 15 is preferably circular in form, conforming to the shape of the flange 14 of the sleeve 13, and may be readily grasped so as to turn the sleeve the desired amount to control the amount of gas to the burner.

Extending through the threaded opening 17 in the cagel is the threaded stem 18 which carries the conical-valve 19 at one end and at its opposite end the hand-wheel 20. The conical valve 19 is in such position with reference to the outer end of the shell or casing as to control the size of the opening into said casing, according to the amount of air to be admitted. The air may be controlled with great accuracy so that just the vproper amount is admitted to mix properly with the gas to cause substantially perfect combustion.

When my improved burner is in use, the gas is admitted from the supply-pipe to the chamber 7, and passes by the apertures 5 into the casing where the air admitted through the mixer unites with the gas, and the same is properly mixed before it arrives at the point of combustion. To make a proper mixture for burning 9.31 cubic feet of air are required for 1 cubic foot of gas. Bymeans of the control of the entrance of the gas by means of the sleeve 13, the admission of gas may be regulated to a great degree of nicety, while by means of the valve 19, the entrance of the air is also accurately controlled so as to admit the proper quantity of air in proportion to gas. Furthermore, by having the apertures arranged spirally by the turning of the sleeve 13, the number of openings uncovered by the sleeve may be readily determined by the distance the sleeve 13 is turned. Then it is once determined how much gas passes through one of the openings 5, the increased amount of gas admit-ted by uncovering other openings may be readily calculated and the amount of air increased accordingly by the movement of the valve 19.

In the above manner, I provide a simple form of burner by means of Which the air and gas are so controlled that they are admitted to the burner in proper proportions, and when the amount of gas is reduced, the air is correspondingly reduced or vice versa, thereby creating a great saving in gas, and at the same time giving the greatest number of heat-units for the amount oit' gas consumed.

My improved burner may be made up in diierent forms and is applicable for use in connection with boiler and heating furnaces of different kinds as Well as hot Water heaters, and practical experience has proven that by its use a great saving is effected in the amount of gas consumed.

What I claim is:

1. In a gas-burner, the combination of a suitable shell, or casing, having apertures formed therein arranged spirally, a chamber surrounding said shell or casing, means for supplying gas thereto, a threaded sleeve surrounding said shell or casing, means for turning said sleeve, means for supplying air to said shell or casing, and means for controlling the supply of air to said shell or casing.

2. In a gas-burner, the combination of a suitable shell, or casing, having apertures arranged spirally, a chamber surrounding said shell or casing, means for supplying gas thereto, a threaded sleeve surrounding said shell or casing, the said apertures being arranged at the same pitch as the pitch of the threads of said threaded sleeve, means for supplying air to said shell or casing, and means for controlling the supply of air to said shell or casing.

3. In a gas-burner, the combination of a suitable shell, or casing, having apertures therein, a chamber surrounding said shell, o1' casing, means for supplying gas thereto, said chamber having a threaded opening, a sleeve engaging said threaded Opening and controlling said apertures, means for supplying air to'said shell or casing, and means for controlling the supply of air to said shell, or casing.

4. In a gas-burner, the combination of a suitable shell, or casing, having apertures therein, a chamber surrounding said shell, or casing, means for admitting gas thereto, said chamber having a threaded opening, a threaded sleeve engaging said opening and controlling said apertures, a cage connected to said sleeve, means for supplying air to said shell or casing, and a valve supported by said cage controlling the air supplied to said shell, or casing.

5. In a gas-burner, the combination of a suitable shell, or casing, having apertures therein, a chamber surrounding said shell or casing, means for supplying gas thereto, said chamber having a threaded opening, a threaded sleeve engaging said opening and controlling said apertures, a cage connected to said sleeve, a threaded stem engaging said cage, means for supplying air to said shell or casing and a conical valve on said stem controlling the supply or air to said shell or casing.

6. In a gas burner the combination of a suitable shell or casing, having apertures therein, a chamber surrounding said shell or casing, means for supplying gas thereto, a longitudinally movable sleeve lon said shell or casing controlling said apertures, a cage connected to said sleeve, means for supplying air to said shell or casing, and a valve supportedby said cage controlling the air supply to said shell or casing.

In testimony whereof, I the said Ross C. HAWK have hereunto set my hand.
